Full moon, warm water, but oxygen is the limiting factor.

Water's at 69.8°F — right at the top of smallmouth range — and the river is running steady at 160 cfs with decent clarity. The catch is DO: the 24h ceiling only hit 4.9 mg/L, which is genuinely tight all day, not just at dawn. Fish may move, but don't expect them to be aggressive for long stretches; time your best efforts toward mid-to-late afternoon and see what the sun can do.
